Abstract (en)
[origin: US2020103379A1] A chromatography column has a column assembly that further includes a column jacket tube and a column liner tube. The column assembly is configured with end fittings that have compression limiting features and are able to withstand very high pressure, such as used in UHPLC, in conjunction with flange portions of the column liner tube that seal the column assembly. The column liner tube may be biocompatible and may have a smooth consistent inner diameter of less than 2 mm, and an inner diameter of 1 mm in particular embodiments. The end fittings for the microtube assembly may ensure durability and reliability by preventing over- or under-tightening.
